Impact of Multiple Detonation Waves on Heat Flux in Rotating Detonation Engines

Rotating detonation engines (RDEs) are currently receiving significant attention for their high propulsive efficiency. These devices often operate under conditions that generate multiple detonation waves. Building on the work of Ladeinde et al. [Supersonic Combustion Heat Flux in a Rotating Detonation Engine, Acta Astronautica 203 (2023) 226-245], this study investigates the influence of multiple waves on the distributions of heat flux in RDEs, which is a critical area for optimizing engine design and enhancing thermal management. Utilizing large eddy simulation, this research analyzes the effects of the interactions between detonation waves on heat flux by comparing single and multiple waves. Additionally, the study examines how variations in wave count and configuration impact the overall thermal loads of the engine. The findings are poised to inform the development of innovative heat management strategies in RDEs, particularly under diverse operational conditions that lead to multiple waves.
